We created this app because we are full time 'technomads' ourselves who rely on mobile data to work remotely. Keeping this app updated is a priority for us, as we depend on it ourselves!

Coverage FAQ:
Q: Why aren't the maps more detailed or released more often?
A: Our map updates require a lot of meticulous labor intensive processing. There's just no practical way to issue a new update every time a new tower is turned on. We monitor new coverage and try to find balance between effort & staying current. This generally means at least a couple updates a year.

Q: What makes 'Coverage?' unique?
A: There are great apps out there that collect user submitted signal reports - we recommend them and use them ourselves. However, those apps are only useful in markets with an active user base. We took a different approach with Coverage? - we needed a tool to at least give us an idea of where signal should be - urban, rural, and out in the boonies.

"this app can be indispensable" -


The maps in 'Coverage?' are provided in partnership with Ookla, and represent proprietary interpretations of the coverage reported by each carrier. You should not rely on the maps in Coverage to be perfectly precise or absolutely timely.

Ongoing map updates have been free - but to support the ongoing development costs, we now allow customers to subscribe to higher resolution maps that will be updated more frequently.

Coverage does not report or predict signal strength (there are great apps out there for that!). We can make no promises as to where you'll *actually* get signal.. there are too many variables - towers, device, terrain, weather, etc.

So… Got Coverage?

Coverage? 2020.6.6 Update
2020-06-21Version History
MAJOR UPDATE: Canadian Coverage Maps! We’re excited to be able to offer ‘Coverage?’ in Canada, with LTE maps now available for the 3 major Canadian carriers - Bell, Telus and Rogers. A one time unlock fee will permanently enable the Canadian maps for all three carriers inside the ‘Coverage?’ app. For US based travelers - be sure to look up which Canadian carriers your US based plans roam onto, and enable the appropriate layers when headed north. Be sure to keep in mind any roaming restrictions or fees associated with your plan. HD or SD Maps: If you have (or add later) the HD Maps subscription, this will apply to the Canadian maps as well - giving you access to higher resolution maps that are updated quarterly. If you do not have the HD Maps subscription, you’ll have access to the standard resolution maps, and will receive map updates on a less frequent basis. UPDATED: Newly updated maps for AT&T, Verizon, T-Mobile, and Sprint. FIXED: Issues with restoring previous purchases, and other bugs. And from the April 2020 app release: NEW: Added maps and support for U.S. Cellular - the nation's fifth largest carrier. TIP: US Cellular does not have native nationwide coverage, and across much of the nations US Cellular customers are actually roaming onto other carriers, and may be subject to roaming usage limits. Use our US Cellular roaming layer to get a better idea when you are out of US Cellular native coverage, and thus might be at risk of running into roaming limits.
